摘要:
A novel class of compounds, i.e., 1,1-bis-H-phosphinates (or 1,1-bis-H-phosphinic acid derivatives) are provided. Also provided are novel methods for producing 1,1-bis-H-phosphinates and 1,1-bis-H-phosphinate conjugates. These compounds and conjugates are used as precursors of bisphosphonates and bisphosphonate conjugates, respectively, or as prodrugs directly for treating bone-related and various other diseases.
